Binman construct images consisting of multiple binary files. These files
sometimes need to know (at run timme) where their peers are located. For
example, SPL may want to know where U-Boot is located in the image, so
that it can jump to U-Boot correctly on boot.

This series implements this, allowing binaries within the image to become
aware of each other without any significant run-time overhead.

It can be used for:
   - SPL jumping to the correct location for U-Boot
   - SPL finding an FPGA image to program
   - U-Boot locating some configuration data (e.g. serial #) in the image

A way to handle this with binman was requested by Marek Vasut some weeks
ago.

As a demonstration, this converts Tegra to use binman to find U-Boot from
within SPL.

Are there any more comments on this please? I plan to tidy up the
Tegra comments and send v2.
